TROLLEY-WJREHANGER.

SPECIFICATION forming part of Letters Patent No. 592,923, dated November2, 1897.

Application filed Tune 28, 1897. Serial No. 642,652. (No model.)

' the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to hangers for electric wires; and its object is toprovide an improved form of hanger that may be readily applied to anelectric wire without the necessity of soldering or brazing and fromwhich the wire may be readily detached when deemed necessary.

My invention consists of certain novel features of construction andcombinations of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of my device.Fig. 2 is an end elevation thereof. Fig. 3 is a side elevation of amodified form of my device.

The numeral 1 indicates the frame of my device,which is composed of twodownwardly-ex tending lateral arms 2 and two downwardlyextending arms 3at right angles to these. Hanger-arms 4 are formed upon the arms 2.Gripping-jaws 5 are pivotally mounted upon a bolt 6, carried in theframe-arms 3. The lower ends of these jaws are formed to clasp a wire,as indicated at 7. A wedge 8, circular in cross-section, is providedwith a screwthreaded portion 9 and head 10. The head 10 fits upon theupper part of the frame and has an arm 11 projecting outward therefrom,said arm being adapted to keep the wedge from rotation when saidhangeris used upon cars. A lock-nut 12 is also held upon this bolt. The upperends of the gripping-jaws are hollow to receive the end of the wedge. Itis now obvious that if'the wedge be inserted between the jaws andscrewed down therein said jaws will be forced apart at their upper endsand brought together at the lower portions, thus enabling them to claspa wire placed between the same firmly.

In the modified form of my device I have shown a form better adapted foruse on straight lines and where the hanger is suspended from armscarried on posts. I thus provide a simple and efficient means toaccomplish the purpose indicated.

It is obvious that many minor changes may be made in the form of mydevice without departing from the material principles thereof. I do nottherefore desire to confine myself to the exact form herein shown anddescribed, but wish to include all such as properly come within thescope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

, 1. In a trolley-Wire hanger, the combination with a frame, of jawsfulcrumed in said frame having upwardly-extending ends and provided attheir lower ends with recesses shaped to grip a trolley-wire, a wedgehavsaid wedge and provided with a downwardlybent end adapted to dropbetween the portions of the frame and form a' lock, and a lock-nutcarried upon said screw-threaded portion, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
